Prefers quiet stretches of river channels, deep pools and floodplain lagoons with aquatic vegetation; may form small shoals; feeds mainly on insect larvae, shrimps, small snails and small fish (Ref. 52193). Known to move up tributaries when they come down in spate and may breed in newly inundated areas (Ref. 13337). Spawns during the rainy season; females carry up to 7,000 eggs; caught by subsistence fishermen and anglers (Ref. 7248, 52193).
偏愛河峽道中安靜的支流，深水池與有水生植物生長的洪泛區瀉湖。 可能形成小的淺灘。 主要吃昆蟲幼生，蝦，小的蝸牛與小魚。 已知向上游支流遷移他們何時在氾濫中下來而且可能在最近浸水的區域中繁殖.(參考文獻 13337) 產卵於雨季; 母魚抱卵向上到 7,000個卵。 被漁民與垂釣者捕獲了。 (參考文獻 7248)

Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
